Hi everyone. I found this forum while trying to solve this problem at my house. I'm in the U.S. and I'm having the same issue. Tonight while watching a recording TiVo just all of sudden switch to YouTube and no one was casting YouTube at my house. This has happened a couple times to me since the box did a update but it's random, maybe 3 times in the last 6 weeks so I'm leaning towards a bug in there system. I'll try a hard reset and see if that works once I've watched all my recordings and have the time to re-enter everything. Removing the Ethernet cable from the Lan port is not really a option because the guide won't stay updated for recordings and randomness of it switching. If I find a solution I'll post it on here.
